Conventional septic tanks vary in shape and size, but are largely the same in internal construction. The traditional septic tank is internally provided with a partition board, the septic tank is divided into two or more reaction chambers, each reaction chamber can carry out solid-liquid separation on excrement, the layers are separated, and finally, clear liquid which can be used for rural irrigation is discharged. However, the cleaning of the residual solid waste after filtration is always a difficult problem, and the current cleaning mode is almost a mode of pumping through a reserved hole at the upper end of the septic tank, pumping the waste in the septic tank into a transport vehicle, and performing composting or direct treatment. However, such a treatment method puts higher requirements on the installation position of the septic tank, needs to be suitable for large or small manure suction trucks to enter, and is difficult to clean the septic tank thoroughly. The solid waste accumulated at the bottom of the reaction chamber for a long time not only can greatly reduce the available space, but also can easily cause blockage of the excrement passing pipe, and simultaneously pollutes the environment and is harmful to health.

Example 1

The septic tank of the embodiment comprises three reaction chambers 1 which are communicated in sequence, and the main structure of the septic tank is made of steel; the first reaction chamber is an anaerobic chamber and is a first-stage reaction chamber; the second reaction chamber is an anaerobic chamber and is a secondary reaction chamber; the third reaction chamber is a clarification chamber and is a three-stage reaction chamber. The volume ratio of the three-stage reaction chambers is 2:1: 3.

The bottom of each reaction chamber 1 is provided with a cleaning door 4, and the top is provided with two pull rings 6.

The top of the first reaction chamber 1 is provided with a 3-5cm high manure inlet 2, the inlet end of a manure passing pipe 3 welded on the inner wall of the side surface of the first reaction chamber is positioned at the 2/3 height of the side wall of the first reaction chamber, the vertical distance between the outlet end and the top of the second reaction chamber is 5cm, the manure passing pipe horizontally extends into the horizontal second reaction chamber for 5-7 cm after passing through an L-shaped through groove at the joint of the side wall of the first reaction chamber and the side wall and the top of the second reaction chamber, and the extending length can not only keep the conduction efficiency of clear liquid, but also ensure the continuity of the whole device; the clamping block 7 is detachably fixed at the through groove, so that the manure passing pipe 3 is fixed, and a notch of the through groove left after the manure passing pipe 3 extends into the through groove is sealed, so that the sealing performance of the reaction chamber is ensured, and the anaerobic reaction is facilitated;
